Hi
Yes you misunderstood one issue.
Previously some patches were required to upgrade between some fw versions : it is the information of this topic
https://plugout.net/viewtopic.php?f=7&t=3059But last month our web hosting provider made some changes on its apache servers and the firmware fails to open a session on plugout.net to download packages (so for installing addons and also for upgrading). Then we posted a new topic
https://plugout.net/viewtopic.php?f=27&t=3532)
Of course I rebuilt the patches available via the topic
https://plugout.net/viewtopic.php?f=7&t=3059 by including the connection fix and also in the current roll-up patch for version 18-2 (patch03) : without it from a version 18-2 you can not install an addon or re-install a fresh version 18-2 and also later upgrading to a newest fw version when we will release one
